ln earnving the invention into electr` there are provided means l'orSupporting a wrapper and an article to be Wrapped therein, and means;lor placing a wrapper in said supporting means with two diagonaltvvopposite corners upstanding and with tvvo diagonally opposite corners?outstanding, or, in other words, in trough-like formation read)Y toreceive the cand)v hara. and nieane for folding thel wrapper about thearticle with its eorners superposed. In the best eonstruetionscontemplated, the supporting means is in the form of a eonvevor having a.series of Supporting pockets, a magazine for the wrappers is providedfrom which the wrappere are successively transferred to the pockets ofthe Conveyor. means for assembling stillening Oradvertising eards withthe wrappers in the pockets are provided. scaling means l'or l'asteningthe `mperposed corners yol the wrappers are provided. nml means forcentering the artieles in the wrappers at'ter a preliminary Wrapper foldhas been made are provided. All ot' the above mentioned parts may loewidelvv varied in eonetruetion within the. Scope of the claims. for thespecilie strueture selected to illustrate the invention in but one olman v possible conerete embodiments of the Same. The invention,therefore.y in not to be restrieted to the precise details ot thestructure shown and described.

The specitie machine selected to illustrate the invention is providedwith a wrapper magazine in which rhoinhie or Similar wrappers arestacked and from which the wrappers are sueeefsfsively Withdrawn bv aturret having suction devices for this pu1poSe,fold ing devices forgiving the Wrappers troughlilte forni. and ejecting deviees t'or plaeingthe trough-like wrappers-in the pockets ol' a conveyor which carries thewrappers with the articles through the several folding devices and thesealingdevice and finally discharges the finished packages.

The articles to be Wrapped are manually placed on the mid-sections ofthe wrappers placed in trough-like formation in the pockets of theconveyor with diagonally opposite corners upstanding and with diagonallyopposite corners outstanding, and hereinafter the first mentionedcorners will be referred to as the `leading and trailing corners, andthe second mentioned corners will be referred to as the side corners. Inpackaging the so-called Baby Ruth candy bars, the leading and trailingcorners of the rhombie Wrapper are obtuse corners, While the sidecorners are acute corners; but in ackaging other articles, the reversemig t be true, Without, however, affecting the operation of the machine.

After an article has been placed on a wrapper in a conveyor pocket,tlieconveyor moves both into the range of action of a folding device whichirst folds the trailing corner of the wrapper down on the article andimmediately thereafter folds the leading corner down on the article overthe corner first folded down. As the conveyor then moves ahead, the twocorners are held in place by engagement of the upper one with aretaining bar which prevents it from springing back away from thearticle. At the next folding station along the path of the conveyor, thepartially wrapped article is centered in its wrapper longitudinally, inorder to insure the proper superposed arangement of the corners of thewrapper which is etl'ecied later on. Then, the protruding parts of thewrapper are folded down on the ends of the article in order to providefor a neat bend which occurs next and in which the previouslyoutstanding side corners of the wrapper are bent upwardly intoiipstaiiding position ready to be folded down on the top of thearticle,`an operation which next occurs, at another folding station.

When the wrapper is completely folded about the article with its fourcorners superposed on the top of the package, a strip of adhesivesealing material is drawn from a reel and applied to the Wrapper where.its corners are superposed, and cut ottI to the proper length. Asuccession of pressing devices then collie into action and hold thesealing strip firmly against the wrapper until the adhesive dries andthe union is permanent.

Then it is desired to insert a piece of cardboard in each package,either for advertising purposes or for stiti'ening the package, thewrapper feeding turret is provided with devices for feeding such cardsto the pockets of the conveyor. The machine selected to illustratetheinvention has such devices.

Referring to the drawings: The machine is irovided with a frame carryinga turret bearing 2o inwhich is slidably mounted and rotatably mounted avertical turret shaft Q7 carrying a turret Q8. The turret Q8 has hollowsuction arms 2t) provided with suction heads in which are slidablymounted plungers 31 and lock rods 32. The upper part of the turret shaftis hollow and carries on its upper end a suction litting 35i heldair-tightly on a fiilcrilni rod til-by a springr 35 resting on a collarfastened to the turret shaft 27. To the latter is slidably keyed a bevelgear iii' driven by a bevel gear 3S mounted on a shaft 3ft) to which isalso secured a (teneva gear t0 driven by a two-arm crank 4l aiid turningthe turret 28 one step in every half revolution. The shaft 3S) ismou'nted in a bearing bracket 42 supported by the frame 25 beforereferred to. The crank 41 is mounted on a shaft 43 to which alsofastened a sprocket 44 driven by a chain 45 from a sprocket 4G on themain drive shaft 47 which is journaled in bearings in the frame 25.

The turret shaft. QT, at its lower end, has a stud 48 carrying a lift4S) operated by a lever 50 mounted on a shaft 51 supported by bearingbrackets 52 attached tothe frame 25. The shaft 51 carries a cani arm 53operated by a roller 54 from a. am on the shaft 47, the

cam 55 swinging the lift 50 up and down, thereby raising and loweringthe turret. 28. The latter turns one-iplarter of a revolution at a timein its raised position, and then descends to its lower position in whichthree lof its arms operate siiiiultaneously. One arin picks up a wrapperfrom the magazine. 5G. the second pushes the wrapper picked up at thepreceding step into a former 5T which gives it its proper trough-likeforni. and the third delivers the previously formed wrapper into one ofthe pocketsxi of the conveyor 5f), the fourth being emptv and ready topick up a wrapper in the next step.-

The. suctiondevices 3l for picking up the wrappersl have a vertical borewith a horizontal port 60, as shown in Fig. G. The lower lends of eachpair of plungers are connected b v a bar (il against which hear springs(i2 surrounding the protruding lower ends of the plungers. opening thesuction ports ($0 when released by the lock rods 32. The latter are heldin locked position by the springs 63 and normally engage a shoulder ofthe plungcrs 3l, thereby preventing them from moving downward` but have,adjacent; the phingers, sections 32" of smaller diameter which, whenpushed forward by an arin (i4 into registrad tion with the plungers.allow the shoulders to pass the lock iod. The plungers are provided withheads 05 having packing collars 0G insuring a sufficient vacuum whilethe wrapper is held on thesuction device.

The turret Q8 is provided with lock hushings 67. each located on one ofthe suction arms 29, as shown in Fig. 3. On the downward movement. ofthe turret, the lock hushings. engage lot-ltpins ttt? (Figs. 7 and 8)and thereby loel; the turret. ln descending tarther, the loek hushingpushes down a tirl-:ed lever (it) mounted on :1 shaft Tt) to whieh isalso fastened the arin (il, and. in so doing, the forked lever (tileoinpresses a, spring T1.

The forni (Figs. 13 and 11) eonsists o1` a torni traine 57fastened to a slide 1111 which lnoves up and down in a hraeltet 1112mounted on the traute 2.7. ()n the slide 101 is mounted a hraeket 11123in whieh slides a rod 104 earrying a form plate 1115 having guide pins106 passing through holesv ot the top plate T ot' the lirarliet 1(123.The forni plate 1115 is held in raised position hy a spring 1(18fastened to a eollar 1111) on the rod 1(1-1.

For inserting stitleliing or advertising eards into the paekages. theturret is provided with arms 126 (Figs. 1. 2. 3 and 4l which carryattachments for placing a card 127 upon each wrapper. Cards are storedon a reel, not shown, mounted on a bracket 128 extending from the baseof the machine, and are pulled over a guide 129 by rollers 130 and 130,`The roller 136 is mounted on a shaftl 131 which is driven by asprocket132 and chain 133 from a sprocket 134 mounted on the conveyorshaft 135 journaled in the rframe 25. On the shaft 131 is mounted a gear136 meshing with a gear 137 on a shaft 138 which carries a roller 130.The shaft 138 is mounted in a lever 139 which is pivoted on a bracket14() and held in tension by a spring 141. The card, before being cut,passes over a small hump on the guide 129 While an adjustable roller129abears against it, thereby taking out its curl from being rolled onthe reel. A knife 142, supported in a bracket 143 and having an up anddown motion, cuts the card material into the required lengths. Each arm126 carries two guide rods 144 holding at their ends a plate 145 havingvertical guide bearings'146 for impaling needles 147. The latter arecarried by a plate 148 mounted on the end of a lifter rod 149 which isslidably mounted in a bearing on the arm 126 and forced downward bysprings 150 surrounding the guide rods 144. When the turret descends,the needles 147 impale and pick up a card, and, in the next step of theturret, transfer the card into the pocket of the conveyor which in thepreceding step received a wrapper. In the downward movement of theturret, the lifter arm 151 of the rod 149 engages a stop bridge 152resting onv an operating table 153 and spanning the conveyor. therebylifting the picker plate 148 and stripping the card from the needles 147by the stripper plate 145.

The conveyor chains run over sprockets 154 mounted on the conveyor driveshaft. 135, and over sprockets 155 fastened to a shaft 156 A supportedin bearing brackets 157 on the frame 25.

In Fig. 1 is shown a detail of the sprocket and "bain arrangement forthe conveyor, the teeth of the sprockets 154 and 155 being cut on a..polygon instead of on a circle, so that the pockets 58 can be fastenedacross two or more links of the chains, thereby holding them much morefirmly than would be possible by attaching them in the usual manner toonly one link. The pockets may span any number of links and may be setany distance lstanding side corners the Wrapper, until folded up, aresuppori'. d by guide shoes 159 fastened to endless chains 166 runningparallel with the conveyor chains. The guide shoes 159 have upwardlyprojecting pins 159n which hold the Wrappers in position in thepocket-s. The chains 160 are driven by sprockets 161 on the shaft 135and run over sprockets 162 and idlers 163. The sprockets 162 are mountedon a shaft 164 supported in the folder bearing brackets 165,'and theidlers 163 are carried by a shaft 166 in the frame 25.

After passing between lthe operating table 153 from which the articlesto be Wrapped are fed upon the Wrappers in the pockets 58 by a manualoperation, the package on the conf veyor next moves under the rotaryfolding segment 167 (Figs. 15, 16 and 17) which is mounted on a shaft168 and folds the upstanding trailing corner ofthe Wrapper down on thearticle. The shaft 168 is supported by a bearing bridge 202. and by abracket attached to a Water receptacle 255. Another curved and rotatingsegment 169, also mounted on the shaft 168, then engages the leadingupstanding corner of the wrapper and lays it down gradually over the rstfolded corner, and holds it down during the advance of the package untilthe now superposed corners come under and are held down by, agravityactuated retaining bar 17e suspended from a vsupporting bar 171mounted on the frame of the machine.

At the end of the next step of the conveyor, the article Within theWrapper and partially enclosed therein is centered by a pair of fingers172 and 173 (Figs. 18 and 19) which are interconnected and enter thepackage through the open ends of the Wrapper. The centering fingers 172and 173 are pivoted on a bearing bridge 202. The finger 172 has a rearextension 174 carrying a pin 175 which engages a slot in a rearextension k176 of the finger 173. To the extension 174, is pivoted a camlink 177 having a roller 178 engaging a cam 179 mounted on ya shaft 180.The cam link 177 is provided with a fork 181 acting as a guideandbearing for the same. As the roller 178 follows the contour of the cam179, the link 177, through the extensions 174 and 176, actuates thecentering fingers 172 and 173, closing and opening the latter, therebycentering the article if off center.

At the next step of the conveyor, two pairs of eccentrically mountedrotary members or discs 182 and 183 (Figs. 2() and 21) turning againsteach other or in opposite directions. close the`ends of the package byfolding-tbe outstanding Wrapper down on the ends ofthe article. Thediscs 182 are mounted on a shaft. 184 supported in bearing brackets 165.and the discs 183 are attached to sleevesA 185 and 186 turning on theshaft 184. The discs 182 and 183 are driven from a sprocket 187 havinglong hub forming a sleeve on a stud Cit 319 attached to the hearingbracket 165. The hub of the sprocket 187 carries a gear 13S which mesheswith a gear 189 on a shat't 19t) in the bearing bracket 165. and also agear 191 mounted on the right hand end ot the shaft 184. ()n its lefthand end, the shaft 184 carries a gear 192 which, through anintermediate gea r 193, drives a. gear 191 on a shaft 195. The lattercarries a gear 196 meshing with a gear1t17 mounted on the sleeve 135.()n the shatt- 19() is also a gear 193 which drives a gear 199 on thesleeve 166. The shaft 134 carries a spiral gear 21)() meshing' with aspiral gear 2tl1 on the sha t't 168 which carries the folding segments167 and 16S). The sha t't 19t). on its imier end. has a bevel gear 2112Kwhich meshes with a bevel gear 204 and thereb v drives a shaft 2117.Likewise. the shaft 195 has a bevel gear 205 meshing with a bevel gear2116 on the shaft 181), thereby driving the latter. The shafts 130 and267 are supported in arms 202s otl the hearinghracket 165. lhih thediscs 1623 which revolve towards the pack age, are circular in shape.the dises 132 which revolve with the package, have an elongated form.the tail part ot' the disc being of such shape as to keep in engagementwith the folds ofthe wrapper and hold them down until the package haspassed to its next position.

At the next step of the conveyors, the outstanding side corners of4 thewrapper. while being guided by two stationary curved plates 269. arefolded upwardly against said plates by rollers 210 (Fig. The plates 209,which are slightly Wider than the conveyor pockets, are fastened'to bars211 mounted on a bridge bar 212 supported by bearing stands 213` as seenin Fig. 23. The folding rollers 21() are carried in forked bearings 214pivot ed on lugs 215 of the curved folder plates 216, the latter beingattached to arms 217 rotating on shafts 180 and 207. The rollers 21()press the wrapper against the plates 209 hy means of springs 218 securedto the arms 217. The folders turn in the direction of the arrows, makingone-.half of a revolution for each package. The folding segments 216hold the upfolded ends of the wrapper against the plates 209 while thepackage is being advanced to the next con veyor station.

1n the next operation, the now upstanding .side corners of the wrapperare folded in overlapped condition over ther previously overlappedtrailing and leadingr corners on the top of the article. For thispurpose, two flexible tapes 221 (Fig. 23) one at each end ot'tllepackage. are fastened at one end to a rod 222 supported on the chainguard bar 223. Die other end of each tape is held by a clamp 4 fastenedto a tension spring 225 which is ,Fringed to a cam lever 226 mounted ona shaft 227 supported b v a bearing bracket 228. The cam levers 226 haverollers 229 engaging, by means of springs 331, Cams 230, one of Which ismounted on a shaft 231 and the other on a shaft 232, these shafts beingJournaled in a stand 213 and in the bracket 228. The shaft 232 isadditionallyv supported in a hearing 233 ina .stand 234. '.lo the stands213 are pivoted guide rails 23; in which are slidably supported hars 236carrying at, their ends the rollers 237. The hars 236 are connected withthe cam levers 226 bv means of rods 238. and the guide rails 235 havecam rolleis 239 engaging cams 21o on the shafts 231 and 232.l 'l'hroughthe ra ui levers 226` the slide bars 236 move the flexible tapes 221 toand from the'package or in and out ot' operative position. and throughthe rollers 239. the bars 236 move the tapes 221 up and down. thecombined action of the cams 23o and 24o pressing the tapes against theends and over the top of the package, thereb \v making the overlap 'ofthe .side corllll'S.

lhile still being held in position bythe flexible tapes 221, thesuperposed corners of the wrapper are served with a strip 241 of gummedpaper or the like which is pressed onto the package by a roller 242supported in a forked lever 243 pivoted on a lever 244. 'hen the roller242 with its gummed strip 241 rests on the paclv'age` the flexible tapes221 are withdrawn and the package is moved ahead` the presser rollertravelingr with and remaining on the package for one step ot the con vevor movement. The end ofthe gummed strip 241 in the meantime is held bya cushion 245 pressing it down on the preceding pack.- age, and when thenew package takes the place of the former under the cushion, so holdingthe strip, a cam lifts the roller 242 from the package and holds it inraised position while another cam brings it back again to its startingpoint.

From the reel 246, the sealing strip, after passing over an idler 247.runs over a feltlined moistening roller 248 which receives its moisturefrom a roller 249 mounted on a shaft. 250 supported in bearing brackets251 and 252 mounted on the bridge bar 212. The shaft 251), through achain 253, is driven by a sprocket 254, the, roller 249 ruiming in awater receptacle 255 mounted on the bridge bar 212. The roller 247 ispivotedV to an arm 256 mounted on a shaft 257 which receives rockingrmotion from acam lever 258 having a roller 259 in engagement with a cam260 mounted on the shaft 250. The latter also carries a cani 261actuating a roller 262 on a cam lever 263 which turns freely on theshaft 257. To the cam lever 263 is fastened a lever 264r to which ispivoted the lever 244 connected to the forked lever 243l carrying thepresser roller 242. The forked lever 243 is swingably supported on alever 265 pivoted on an arm 266 mounted on a bracket 267. The arm 266has a lever 268 which, through a connecting rod 269, is connected with a.l joined together vby a strip 331 and are supi 332 from a crossplate333- vsupported by supporting lever 265. The cam '260 pushes` thepresser roller 242 forward, while the caln 261 raises it for rearwardmovement.

The cushion 245 which holds the gummed strip 241 Vwhile it is being cutby the knife 270, and the cushion 271 which presses down on the strip atthe next step of the conveyor, are mounted in shells 272 (Fig. 1) heldby vertical rods 273 which slide in bearings 274 mounted on a crossbar275. The upper ends of the rods 273 are connected together by bars 276which are attached by springs 277 to the crossbar 275. Stop collars 278prevent the rods 273 from sliding down too far. The strip'cutting knife270 is attached to the crossbar 275, as are also the flexible tapes 279which in the last two steps of the sealing operation press down and sealthe ends of the gummed strip 241 on the package. Each lfiexible tape 279is held between two fingers 280 which are pivotcd on the crossbar 275and tensioned by springs 281.A

The crossbar 275 is supported by a bracket 282 fastened to a slide 283which is held in a guide block of the bearing stand 234 mounted .on acrossplate 284. The slide 283 has a lug 285 which, through a link 286,is connected to a cam lever'287 pivoted to a lug 288 of the stand 234and engaging, through a roller 289, a cam 290 mounted on the shaft y232.The cam 290, through the cam lever 287, imparts to the crossbar 275,and, with the latter, to the cushions 245 and 271, knife 270, andA tapes279, an up and down motion in synchronism with the step movement of theconveyor.

The reel 246 of the sealing strip 241 is the bracket 267 supported onthebearing stand 234. The roller bracket 267 has an extension 291 towhich is fastened a tape 292 which rests on the perimeter of the roll ofsealing strip and carries a weight 293, thus acting as a friction brakefor the unrolling strip.

After being sealed, the package is ejected from the conveyor by an arm294 mounted on a shaft 295 which is supported by a bearing bracket 296fastened to the frame25. On the shaft 295 is fastened a. crank 2 97connected by a rod 298 to a crank 299 on the shaft 51 which is kept inrocking motion by the cam 55. The ejector arm 294 pushes the finishedpackage .between two horizontal brush-studded plates 300, the brushesholding the seal down smoothly while in-the drying stage. Thebrush-studded platesare ported by-studs caried'by brackets 334 attachedto the end of the frame 25. They are made of sufficient length to allowthe package seal to thoroughly dry before final ejection from themachine.

The machine is driven from a belt 301 ,running over a main pulley 302mounted on the drive shaft 47. A sprocket 303% the lshaft 47, through achain 304 and sprocket 305, drives thc shaft 94 carrying the cams 93 and306. The chain 304 is held tight by an idler 307 turning loosely on theshaft- 51. The cam 306, through a roller 307, actuatcs the cam lever 308pivoted to one arm of a bellcrank 309 mounted on a shaft 310 supportedin the frame 25. The other arnl of the bellcrank 309 is connected, by alink 311, to a` lug 312 of the card cutting knife 142, thereby operatingthe latter. On the shaft 47 is also mounted a sprocket 313 which,through a chain 314, drives the sprocket 315 on the shaft 124, thelatter having a sprocket 316 driving, through a chain 317, the sprockets187 and 318. The sprocket 318 is mounted on a shaft 320 and, through aspiral gear 321 meshing with a spiral gear 322, drives a shaft 232. Onthe shaft 320, which is supported in bearin'gbrackets 323 attached tothe frame 25, is also mounted a spiral gear 324 meshing with a spiralgear 325 on the shaft 231. The hub of the sprocket 187 carries asprocket 326 which, through a chain 253, drives the sprocket 254 on theshaft 250. 0n the rocking arm 256 is loosely pivoted a. gripping paWl327 resting on the gummed strip 241 on the. roller 247 some distancebeyond its highest point. As the presser roller 242 moves forward withthe package, the pawl 327, through the backwardmotion of the arm 256,clamps the strip 241 to the roller 247 and pulls off a length vof stripsufficient for one seal, from the reel 246. The length so pulled offforms a slack in the strip which is taken up by the return motion of thepresser roller 242. For making the necessary adjustments in assemblingthe ma'- chine, the drive shaft 47 is provided with a hand Wheel 328 formanual operation. The pipe 329 communicating with the suction chamber ofthe turret 28 is attached by a hose connection 330 to a suction pump,not

shown. The operating tables 153 are supported by posts 335 fastened tothe frame 25 of the machine.
